Characteristic
Ammonium polyphosphate
(APP) is avirulent
insipidity, and do not produce the corrosive gas, hot high
stability, is a fine performance non-brine flame retardants. Mainly
used as flame retardant. Product P and N content high, thermal
stability and chemical stability performance is good, water-soluble
and suction wet sex small, product close to neutral, low toxicity
(LD P *0g/kg). APP in polyurethane hard vesicles has a high flame
retardants, dimension stability, heat-resistance and resistance to
hydrolysis. Ammonium polyphosphatehave expanded
flame retardant function. APP in addition to apply to the rigid
polyurethane foam plastics and polyester soft polyurethane foam
plastics outside, also applies to other resin, adhesives and
coatings.
It can be divided according to the degree of polymerization size,
low, gather together three high, The degree of polymerization is
larger, water-soluble small, According to the structure can be
divided into the crystalline form, and functional crystal together
for water soluble ammonium phosphate, and there are gathered the
v-shaped five.
Application
Mainly used in fire coatings, plastic, rubber, wood, paper and
other materials of flame retardants, Can a dual compound
fertilizer, as high feed additives, liquid detergents, adhesive,
ion exchange.
Storage and Packing
